Nasal duche

ABSTRACT

The invention is directed to a device, therapeutic liquid and method which facilitates a stream of liquid being introduced forcibly or by inhalation through a patient&#39;s nostrils into the nasal cavities of a patient&#39;s head essentially while the patient&#39;s head and neck is tilted forward at an angle from its vertical upright position to facilitate excess amounts of liquid leaving the nasal cavities at the back to enter the back of the oral cavity and mouth without entering the airway below including the trachea and the lungs.

FIELD OF THE INVENTION

[0001] This invention relates to a method, device and liquids for introducing a stream of liquid into the nasal cavities of the head.

BACKGROUND OF THE INVENTION

[0002] The application of liquids to the membranes lining the nasal cavities of the head as a means of treatment is well known. Heretofore, at least three methods are known to accomplish this using three types of devices. One is to spray liquid into the nostrils where the liquid is of thin consistency and another is to administer drops into the nostrils where the liquid may have a thicker consistency or is an oil. Another device, the subject of U.S. Pat. No. 5,417,652, May 23, 1995, which is a cup that facilitates inhaling a liquid while the nose is inserted in a specially shaped opening in the side wall of the cup while the patient's head is maintained in an upright position. One drawback of each of these devices and methods of use require distribution of small quantities or mists of the liquid within the nasal cavities, and inhalation while the head is in the upright position allows exposure of possible entry of the liquid into the windpipe and lungs. Another drawback is that immersion of the nasal cavity membranes for sustained periods or to uniform concentrations of an ingredient within the liquid by any of these methods or devices is not possible. None of these methods allow a stream of liquid to be passed into and through the nasal cavities.

[0003] Methods of forced streams of liquid have required the liquid be removed by suction or allowed to drain back out the nostrils. These methods do not provide a means for replacement of the air in the nasal cavities with the liquid and require intrusive tubes and hoses be inserted into the nostrils and the nasal cavities exposing the recipient to injury.

[0004] Another method is known to be used during surgical procedures to areas of the nasal cavity as a means of preventing drowning or drainage into the lung using a plug at the posterior opening of the nasal cavity by a procedure of inserting a string through the mouth up through the nasopharynx and through the nasal cavity and out the nares of the nostrils, attaching the plug made of some material to the end of the string exiting the mouth, then pulling the string at the nasal end pulling the plug through the mouth and out the rear entrance of the oral cavity and into and plugging the nasopharynx and thus prevent liquids, such as blood or irrigation liquids, from entering the pharynx and the lungs. The patient is laying in the face up position during this procedure.

SUMMARY OF THE INVENTION

[0005] It is an object of this invention to provide a method for safely introducing a stream of liquid into the nasal cavities of the head equivalent to a douche for the nasal cavities of the head and extruded through the mouth or back through the nostrils. It is an object of this invention to provide a method for infusing, permeating, bathing, soaking and flushing all or a portion of the nasal cavities of the head with liquid and allowing any excess of liquid to exit the rear of the nasal cavities and pass over the soft palate and into the mouth without entering the lower airways of the trachea and lungs and exiting either through the mouth or back through the nostrils. It is also an object of this invention to provide a choice of liquids and devices suitable for the method.

[0006] Briefly, the invention is directed to a nasal douche, a device, therapeutic liquid and method which facilitates a stream of liquid being introduced forcibly or by inhalation through a patient's nostrils into the nasal cavities of a patient's head essentially while the patient's head and neck is tilted forward at an angle from its vertical upright position to facilitate excess amounts of liquid leaving the nasal cavities at the back to enter the back of the oral cavity and mouth without entering the airway below including the trachea and the lungs.

DETAILED DESCRIPTION OF THE INVENTION

[0011] Anatomically, each nasal cavity of the head naturally contains two openings, the nostrils at the front and the nasopharynx at the back such that if the head is held upright, each are at approximately the same horizontal level. While it is possible to close the back opening through muscular action, doing so naturally prevents sucking a flow of liquid through submerged nostrils by inhalation or forcing a flow a liquid which requires replacement of the air with liquid. It is well known to anyone who swims underwater that closing the back opening prevents liquid from entering through the nostrils by preventing replacement of the trapped air.

[0012] Whereas, if the patient is laying in the face down position, any liquids draining from the nasopharynx over the soft palate past the rear entrance of the oral cavity must drain down into the rear of the oral cavity by force of gravity. Any position between a vertical head and the face down position, herein referred to as a forward tilted position, imparts the same effect as the face down position by effectively placing the entrance into the back of the oral cavity on the floor of windpipe and functioning as a drain into the oropharynx.

[0013] This invention exploits the benefits of positioning the head and neck and therefore the pharynx in a forward tilted position. It may be observed that maximum benefit is received if the patient is in the face down position. However, any forward tilt of the head tends to place the rear opening of the oral cavity along the floor and in the drain position along the path of any liquids passing from the nasopharynx, if the angle of the tilt is at least sufficient to cause the liquid to adhere by force of gravity to the anterior wall of the pharynx.

[0014] If a liquid is allowed into the nasal cavities of the head and the head is kept in an upright position, not only does the liquid leave by way of the nostrils, but to the extent any does exit through the back of the nasal cavities, the liquid naturally flows straight down by force of gravity to either be swallowed, to be passed into the lungs or to be expelled by uncontrolled reflexive coughing as it enters into the pharynx and windpipe. This is a survival mechanism to prevent liquids reaching the trachea, bronchia or the lungs.

[0015]FIG. 4 illustrates that if the head is tilted forward, the nostrils tend to effectively become the bottom of the nasal cavities and the back effectively becomes higher and thus the effective top of the container formed by the nasal cavity. It should be noticed that if the head is tilted at any angle greater than approximately forty five degrees for the average person, though the angle may vary, the nasopharynx effectively becomes the absolute top of the cavity. Stated another way, at that forward angle approximately half way between vertical and horizontal, the rear exit of the nasal cavities rises vertically above any of the regions of the nasal cavity and the nostril lower than any part thereof to effectively become the bottom. With this observation, it may be seen that between a forward tilt which is almost upright to an angle which is almost forty five degrees, a variable degree of the front and lower regions of the nasal cavity will be in contact with the liquid contained therein, provided that constant suction or force is maintained in the nasal cavity or a continuous flow or stream of liquid is maintained.

[0016] Further, if liquid does escape through the back of the nasal cavity and down the windpipe, if the head and neck are tilted forward, anatomically the opening into the mouth is effectively found along the floor of the windpipe and the liquid drains into the mouth rather than continuing further along the windpipe.

[0017] This invention is intended to take advantage of the foregoing facts. If one attempts to flood the nasal cavities of the head with a stream of copious amounts of liquid but fails to lean the head forward, one possible result is that the recipient of the liquid will drown or suffer induced uncontrollable coughing and choking, and if the intended purpose is to infuse the nasal cavities with the liquid, the attempt would fail since the liquid would simply flow along the floor of the nasal cavities along the hard palate, and out the back opening without infusing the upper regions of the cavities, which is illustrated in FIG. 3. The simple measure of tilting the head forward places what has been termed the back opening of the nasal cavities toward the upper regions of the cavities while at the same time facilitates the safe exit of any liquids that may pass through the back opening by dropping through what has by the maneuver effectively become the floor or bottom of the pharynx into the oral cavity so that the liquid may pass safely out through the mouth.

[0018]FIG. 1 illustrates a device to be used as a inhalation means of introducing a stream of liquid using the method of the invention. It is to a device which is a cup that allows the nostrils to be submerged while the head is tilted forward at a prescribed angle depending on the regions of the nasal cavities desiring to be covered with the liquid. To the extent that the user is a patient and the use is being supervised by a person observing and assuring that the head and neck remain tilted, many other means for submerging the nostrils using various contemplated devices, including a bowl, pan or tube with a diameter large enough for the head to be inserted and the nostrils to be submerged, or tubes or hoses inserted into the nostrils and the nostrils pinched to form a seal around the device. Any of these means would satisfy the means of introduction of liquid within the meaning of the methods of claim 1 and claim 2.

[0019] If the user is instructed on the requirement of the method that the head remain tilted and the user is able to discern that his or her head is in fact tilted, most any means of introduction using the method is safe. However, it is the intent of the devices in claim 3 and of claim 4 with its dependent claim 5, to assure that the head remains tilted to the extent possible in a prescribed position. This safety feature is achieved by one or a combination of mechanisms.

[0020] It is presupposed that a user will sense misuse of a device if the device is leaking over the edges in the case of the cup device of claim 3 or out the mask rim seal in the case of the mask device of claim 4 and will adjust the angle of inclination of either the head or the device to avoid such leakage.

[0021] During usage of the cup device of claim 3, the side wall during inclination effectively serves as an open trough in which the liquid flows such that the curvature of the side wall provides effective trough walls gradually reducing in height toward the user's face due to the diagonal cut at the rim of the cup. By specifying that the trough depth be only deep enough to submerge the nostrils and that there be a seal along the user's face just under the nose and up the cheek along the arc or wide u-shape cut unto the side wall FIGS. 1 and 2 at label 1 only at angles between the cup and face that are less than ninety degrees achieves the desired result of having leakage at the seal or along the trough walls while the head is upright while the cup is tilted backward toward the user with sufficient tilt to submerge the nostrils but not while the head is tilted forward while the cup is tilted backward toward the user.

[0022] In the case of the mask device of claims 4 and 5, a more brute force approach is used by simply having the flow of the liquid be shut off if the tilt of the device is such that a seal along the rim of the mask with the face is possible while the head is more upright than a specified tilt and not in the upright position, such that both the flow and the seal will exist only while the head is in a specified or greater than specified tilted position. In other words, as depicted in FIG. 3 if the user has his head in the hazardous upright position, he or she will find that either there is no flow of the liquid or that he or she is unable to create the seal along the rim of the mask with the face. The method of claim 2 provides that the lower regions of the nasal cavities may be the target of the liquid depending on the angle that the head is tilted. By varying the angle of the mask or the angle that the valve shuts, either on the same device or on different devices, the regions may be prescribed with some precision.

[0023] The procedure requires that the user be prepared to receive the liquid into the mouth from the rear at the oropharynx, by during the inhalation procedure, making room for the liquid in the mouth and to be prepared to spit it out, preferably into a sink or bowl as the mouth fills. The liquid may be retained in the nasal cavity by voluntary muscles in the nasopharynx while emptying the mouth or allowed to drain through the nostrils and the mouth simultaneously.

[0024] Claim 3 provides that an arc or unshaped cutout in the wall of the cup be provided to fit the face of the user below the nose and above the upper lip and also provides that the seal not be effective while the angle of cup during submergence of the nostrils not equal or greater than ninety degrees thus assuring that the head is tilted forward while at the same time the nostrils are submerged in the liquid of the cup.

[0025] It should be observed that a cross sectional view of the skull of different persons at the level just below the nose and above the upper lip will reveal that the curvature along the front differs, herein referred to as the face curvature, but is substantially in the shape of an arc or u-shape. The requirement that the angle of the back portion of the side wall of the tilted cup to be less than ninety degrees with the front of the face is made to assure that both the head and the cup are tilted during use, and to achieve this feature, the cutout arc or u-shape in the back of the side wall must be larger than the face curvature such that the face curvature forms a fit and thus a seal only with the aid of the curvature of the cup side wall by virtue of the acute angle. Therefore, for smaller diameter cups, the cutout arc or u-shape may be substantially non-existent to achieve the seal during proper use while for larger cups, the cutout arc or u-shape must be greater. The flexible side walk feature for aiding in the submergence of the nostrils during use effectively increases the curvature of the side wall to approximate the curvature of a smaller cup. It should be observed that with smaller cups, the flexible side wall may not be required while with larger cups, the need for flexibility may be greater.

[0026] It should also be noticed that the diameter of the side wall of the cup is relevant only with regard to how the cup fits against the face, but the size of the cup is relevant with regard to the amount of liquid to be used. Therefore, the cup device need not have side walls that are straight, that is, there may be provided a pot or bell that may or may not be symmetric in shape in the bottom regions to allow for greater volume of liquid while still providing a narrower diameter at the top and still achieve the desired effect with respect to the safety features involving fit and overflow set out herein.

[0027] It should also be observed with regard to selecting one or the other nostril with use of either of the devices claimed in claim 3 and claim 4, a flexible side wall is only one way of achieving this feature. If the device is shifted from one side of the face more toward the other, it has been found that the side of the trough of the cup device referenced herein, or the cheek seal of the mask device, will tend to shut one or the other of the nostrils. Some flexibility is desirable for the purpose of helping the device fit against the face even though not absolutely necessary for nostril selection.

[0028] The presupposition that leakage is a warning signal to the user of misuse is exploited by providing that the liquid overflows the rim using the cup device of claim 3 or breaks the seal between the mask and the face which is formed by the mask rim and the flesh below, along side and over the nose of the device of claim 4, FIGS. 3 and 4, label 2, or that a trap door or other form of gravity actuated valve such as a ball or mercury switch, sensitive to the angle in which the device is being held shuts as in the device of claim 5 illustrated in FIG. 3 label 4 while the liquid may possibly enter the nose without leaking and flowing out of the mask due to the existence of the effective seal when the head is not tilted or in the case of the closed system where the liquid is forced into the nasal cavity as illustrated in FIG. 4, a valve prevents the device from being tilted beyond a prescribed angle during flow of the liquid and the angle of the fitted mask is such that the head must be safely tilted while the flow of liquid is allowed by the valve and the fixed angle of the mask prevents the flow into the nostril due to leakage at the rim of the mask at the seal unless the head is tilted while the valve is open.

[0029]FIG. 2 illustrates the use of the device described in claim 3. This also contains a safety feature, one that encourages the user to use the device while the head is safely tilted as prescribed by the methods of claim 1 and claim 2. A cup at label 8 having a diameter smaller than the size of a user's head is most convenient and is preferred, and substantially smaller is most preferred, so the side wall is cut at an angle along a diagonal plane to form the rim to allow for both the cup to be tilted back which is necessary to cause the liquid to flow toward the face, and the head to be tilted forward which is necessary to satisfy the method of the invention in claims 1 and 2. In FIG. 1 the location shown at label 3, is the lowest point of the side wall defining the maximum amount of liquid to be used, though graduations for lesser amounts may be provided. Label 1 of FIG. 1 shows the cutout in the wall that forms a fit along the upper lip of the user, in the tilted position. If the diameter of the cup is small, the cutout and the curvature of the side wall shown as label 4 of FIG. 1 effectively forms a trough having side walls to prevent the liquid from spilling out laterally during use while allowing enough depth of liquid to submerge the nostrils. If the cup has a large diameter or the shape of the nostrils or the shape or size of the nose should tend to prevent the nostrils from being submerged during use, the side walls of the cup are flexible to allow the thumb 5 and forefingers, not shown, to squeeze the cup effectively increasing the arc or u-shape, that is, decreasing the radius of the arc and the u-shape, of the line of the vertical seal under the nose above the upper lip. The upper portion of the arc or u-shape tend toward the cheeks of the user alongside the nose and is referred herein as the cheek seal shown in FIG. 2 at 4 showing a -short cheek seal as a safety feature in the that the depth of the effective trough formed by the side walls of the cup should not be so deep as to allow the head to be upright without spilling the liquid. The depth of the cheek seal is adjusted by the user by squeezing the side walls.

[0030] A description of the device as a cup is an abstraction that allows description of the critical features, FIG. 1 being the angles of use, the volume before use, and the volume of the liquid contained in the tilted position defined by the top of the cheek seal of the device on the user's face approximately along the sides of the nose with the rim and the seal along the lower lip below the nose and the rim. A pot abstraction could be used coming from the appearance of the device that is comparable to the shape of a coffee pot having a pour spout. A creamer pitcher would be equally applicable illustrating that the shape of the device may vary to be more aesthetically presentable if the functional aspects are met at the contact points on the face and the safety features are met if prescribed.

[0031] The device of claim 3 contemplates a round cup, that is, a perpendicular plane through the cup would be round and having a diameter small enough that an effective wall is formed by the rounded floor of side wall while the cup is in the tilted position, effectively such that the diagonal cut rim geometrically forms a trough with a rounded floor connecting the cup with the seal formed at the face, but if the cup is very large in diameter or the side of the cup is flattened where the cutout fits against the face between the upper lip and below the nose, an additional element would be required, that is that the trough must have walls to prevent the liquid overflowing the edges of the trough gradually increasing in height in the direction away from the user, forming what has been herein referred to as the cheek seal where it contacts the face.

[0032] One feature of the device of claim 3 is that the fit of the seal below the nose allows the nostrils to be submerged only when the head is tilted forward and overflows the rounded wall rim or the cheek seal of the device when submergence of the nostrils is attempted while the head is upright. The cup may be of any shape so long as the functionality of the device is present, so that if the diagonally cut rim is implemented as a trough having a floor and walls to allow the flow of the liquid from a container to the nostrils, the walls of the trough are higher nearest the container and reduced to a height where facial contact is made at the cheek seal is just sufficiently high to allow the nostrils to be submerged. The invention contemplates the walls of the trough extending upward alongside the nose fitting against the cheek of the user with the wall being diagonally cut at an acute angle with the floor of the trough away from the user thus forcing the user to tilt the head forward in order to form the necessary seal during use while the container and its attached trough is tilted back toward the user.

[0033] Another implementation prevents flow when the head is upright as in FIG. 3 and also restricts the device to usage while the head is tilted forward shown in FIG. 4 and is the subject of claim 4 and claim 5, where the liquid is either sucked or forced into the nasal cavity through the nostrils by inhaling with the mouth closed, reduction of volume of a closed sealed environment as with the use of a syringe or bulb, or by gravity flow as in an ordinary douche bag, or increases the volume of the liquid as with a pump in sufficient quantity to fill the nasal cavity to the level on the horizontal with the nasopharynx with any additional quantities entering into the nasopharynx where it flows on the soft palate into the mouth of the tilted head through the back of the oral cavity at the oropharynx by gravity flow before reaching and without entering the laryngopharynx, trachea and the lungs.

[0034] Claim 4 describing a closed system between the container and the mask seal but features no safety elements such as that of claim 5, as illustrated in FIG. 4. The conduit is labeled 5 in both figures, having two exits, 8 and 2. The rear exit of the nasal cavity is at label 7. The valve in FIG. 4 is hinged at label 4 and forms a seal at label 5 which a ring against which the flap at label 6 closes by force of gravity to prevent injection of the liquid. The container opening labeled 8 can lead to a syringe, a squeeze bulb, bag of liquid or even an open cup of liquid so long as the interior space is closed by being submerged effectively causing the system to be closed, sealed and connected. The angle of a line between label 3 and label 1 with the conduit and the angle at which the valve is closed is such to force the head to remain in a tilted position or else the valve shuts and prevents flow of the liquid while the head is in the hazardous and ineffectual upright position, while allowing flow at all angles of head tilt greater than that at or near the upright position. The device in FIG. 4 and claim 4 and claim 5 is most useful if the head is desired to be in a completely horizontal position. It is preferable that the nasal mask be flexible enough to allow the seal to be assured around the nose by the user pinching and shaping it and pinching either side to select the nasal cavity to be open if only one is desired.

[0035] The method of claims 1 and 2 would equally well contemplate using a tube or hose placed into one or both nares of the nostrils and then have the nose pinched to form a seal around the hose or tube, so that if the tube or hose were at a fixed permanent angle, the valve of FIG. 3 and 4 would be effective as a safety feature performing as in claim 5. Claim 5 however describes a less intrusive device being a mask that fits over the nose forming a seal labeled 1, 2, and 3 which either breaks, meaning that it leaks, when the head is upright or the valve closes to prevent further flow, such that the liquid is contained in a nose shaped impermeable mask pressed against the face with a rim shaped to form a seal around and enclosing the nostrils on the surface of the face along the line of contact below the nostrils and along the cheek laterally and over the bridge of the nose. FIG. 4 illustrates the device in the proper position during use.

[0036] Claims 6 and 7 are liquids for the methods in claims 1 and 2 which are unlike any other liquid contemplated before without the method. The liquids of previous nasal methods need be concentrated into a single drop or two, or a spray requiring them to be concentrated and have variable concentrations throughout the treatments as they are disbursed. The method of claims 1 and 2 and therefore use of the devices of claims 3, 4 and 5 may just as effectively be either aqueous or oil and be prepared at any desired constant concentration. Highly calibrated constant concentrations may now be prepared to expose all surfaces of the nasal cavity, whereas before, the concentration of the spray or drop was the maximum that could be tolerated at the point of entry. Of course some preparations require an oily medium while others require aqueous depending on how the ingredients dissolve. Further, the method allows controlled duration of exposure and quick elimination, such that a strong solution could be introduced and removed followed by a wash to eliminate further exposure. Studies of absorption rates and tolerances have not been undertaken but would be helpful in formulating prescribed solutions and usage using the methods and devices of the invention.
